Do you have jumper wires, assorted passive components, a soldering iron, multimeter, and other assorted prototyping basics and consumables?

Also, expand on the pressure aspect of what you want to measure. Let's make sure the BMP388 is a good fit for your application. You mention of 2 PSI caught my eye as an odd specification. It's too low for ambient air pressure and if you're looking for a measurement of overpressure or sound pressure... well 2 PSI is something you'd get from an explosion. The minimum senstivity of the BMP388 (~0.8 Pa) is only going to resister pressure perturbations from sounds louder than what damages human hearing.

The pressure being measured is inside a set of bagpipes. They typically play at up to 40” water (around 2psi) above atmospheric pressure.

I have done DIY electronics before, but in the realm of high-end tube amplifiers, etc. I have jumpers, a breadboard, passives, and a good multimeter already. The new thing for me will be using and tweaking the programming side of the project.

So what I am trying to create is a system for gathering data on how much a reed fluctuates in pitch due to changing pressure applied to it.

I had thought of a simple pressure logger while recording sound separately on a Zoom recorder, then combining both sets of data manually. However, that seems really awkward compared to simultaneously time-stamped pressure and pitch data that can be brought directly into a spreadsheet.
